Unable to connect to stash when running as a service

I run stash as a service under Windows Server 2003. I am able to access Stash homepage (http://localhost:7990/login) when in the Windows Server machine, but unable to do so on a network computer and unable to clone. I can, however, do these when I start Stash using "start-stash.bat" command.
